Browse Forums Heating, Cooling & Insulation 1 Nov 05, 2023 3:15 pm Hey all, I'm looking to insulate the underfloor of my home. The house was built in the 1950's and the floor joists were installed with ~455mm spacing. Ideally I'd like to use polyester rolls to insulate and from what I have found most come in 450mm width to accommodate normal 430mm floor joist spacing. Has anybody found a polyester product that suits wider spaces? If anybody has any other insulation solutions for wider floor joist spacing I'd love to hear it! Thanks!
